16mm isikulufu ishubhu yokuhlola

Leli shubhu lokuhlola le-COD liklanywe ngokunemba nokusebenza engqondweni. Inesakhiwo esimangelengele esingamelana nobunzima bokuhlolwa kwe-COD, okuhlanganisa amazinga okushisa aphezulu kanye nokuchayeka kumakhemikhali ahlukahlukene.

Ishubhu yokuhlola ye-COD engu-16mm ekhiqizwa i-Aijiren isetshenziswa kakhulu ekuhlaziyeni amakhemikhali elabhorethri. U-Aijiren ukholelwa ukuthi i-COD Test Tube idinga izinto ezingavuthiwe zekhwalithi ephezulu kanye nobuchwepheshe obuthuthukisiwe ukuze iqedele ukukhiqiza, ngakho i-Aijiren ibheka kakhulu ukukhiqizwa kwe-COD Test Tube. U-Aijiren uke waba umakadebona emkhakheni wezinto ezisetshenziswayo ze-chromatography oneminyaka engama-20 yesipiliyoni sokukhiqiza. Usayigcinile inhloso yakhe yasekuqaleni futhi ubeka ukuthuthukiswa kwekhwalithi yomkhiqizo endaweni yokuqala.

I-Aijiren ikhiqiza i-COD Test Tube yokuhlola izinga lamanzi. I-COD Test Tube ingasetshenziswa ezinhlobonhlobo zamathuluzi okuhlaziya. Ngenxa yokuthi ukuhlaziya kudinga ukushisisa, ama-reagents ku-COD Test Tube adinga ukushisisa izinga lokushisa eliphezulu noma okunye ukusabela kwamakhemikhali okunamandla, okuthinta ikhwalithi yengilazi. Ngezidingo eziphakeme, i-Aijiren isebenzisa ingilazi engasebenzi kahle yekhwalithi ephezulu ukuze ikhiqize i-COD Test Tube, eyenza kube lula ukusabela kwamakhemikhali.

Amashubhu okuhlola we-COD akhiqizwa i-Aijiren avame ukusetshenziselwa ukuthola isidingo samakhemikhali komoyampilo. Ingilazi esetshenziswe ku-COD Test Tubes ekhiqizwe i-Aijiren inokumelana nezinga lokushisa eliphezulu, ukumelana nokugqwala, futhi ingawavikela kahle amasampula ngaphandle kokuthinta imiphumela yokuhlola. Izinto zokusetshenziswa ze-Aijiren zingezekhwalithi ephezulu kanye nesipiliyoni sokukhiqiza Ngokuchichimayo, ngamanani omkhiqizo avumayo, ingumnikezeli wekhwalithi ephezulu wezinto ezisetshenziswayo zechromatographic.

Isidingo somoya-mpilo wamakhemikhali siwukuhlola okubalulekile kokuhlola ikhwalithi yamanzi alahlwayo kanye namanzi angcolile ngaphambi kokuba akhishwe. Ukuhlolwa kweChemical Oxygen Demand (COD) kubikezela isidingo somoya-mpilo kumfucumfucu futhi isetshenziselwa ukuqapha nokulawula okuphumayo, kanye nokuhlola ukusebenza kwezitshalo zokwelashwa. Umthelela wokuchitheka kwamanzi angcolile noma angcolile emanzini atholwayo ubikezelwa ngesidingo sawo somoya-mpilo. Lokhu kungenxa yokuthi ukukhishwa komoya-mpilo emanzini emvelo kunciphisa amandla awo okulondoloza impilo yasemanzini. Ngakho-ke ukuhlolwa kwe-COD kwenziwa njengenjwayelo kumalabhorethri ezinsiza zamanzi nezinkampani zezimboni.

Ngokuhlolwa kweshubhu ye-Aijiren COD, umsebenzisi ngamunye angakwazi ukuthola kalula amanzi azwela kakhulu futhi anembile.
Isikhathi esidingekayo senqubo yokulinganisa sifinyezwa kakhulu, ikakhulukazi ekuhlaziyweni okujwayelekile kanye nesilinganiso sochungechunge, kuyilapho kunciphisa kakhulu umsebenzi.
Ishubhu yokuhlola ye-COD iqukethe umthamo oqondile we-reagent. Ngakho-ke, inani lamakhemikhali eleqile liyagwenywa futhi nokuphepha komsebenzi kuyathuthukiswa.

Imininingwane Yokuhlolwa Kwesidingo Se-Chemical Oxygen:

U-2mL wesampula wamanzi noma we-watse wengezwa eshubhuni yengilazi engu-16mm equkethe into evuselela ukugaya ukudla kanye ne-catalyst. Ishubhu imbozwe nge-polypropylene, ikepisi elayishiwe ye-PTFE futhi ishisiswe ku-block digester ku-150C amahora angu-2. I-chromium ye-Hexavalent ewolintshi yehliswa ibe yi-chromium e-trivalent eluhlaza okwesibhakabhaka. Ibanga lokuhlaziya lendlela ye-spectrophotometric ngu-5-150ppm (kukalwa ku-420nm).
